Node.js

Q1: What do you mean by Asynchronous API? ☆☆

Answer: All APIs of Node.js library are aynchronous that is non-blocking. It essentially means a Node.js based server never waits for a API to return data. Server moves to next API after calling it and a notification mechanism of Events of Node.js helps server to get response from the previous API call.

	The parser below is a predictive, recursive-descent parser. The use of a predictive parser
	is possible because JSON has an LL(k) grammar. Specifically, JSON has an LL(1) grammar,
	a fact that is hinted at in the `parse_json` function: `parse_json` looks ahead by only
	one character (not even a whole JSON token) in order to decide how to parse the string.
